A cube's side measures 6xy inches whet is the volume

liubo4ka [24]

For a cube, $V = s^3.$

The volume is the cube of the side length.

$V = s^3$

$V = (6x^6y^8)^3$

To raise a product to an exponent, raise each factor to the exponent.

$V = (6^3) \times (x^6)^3 \times (y^8)^3$

To raise a power to a power, multiply powers.

$V = 216x^{18}y^{24}$

What is an example of when you would want consistent data and, therefore, a small standard deviation?

steposvetlana [31]

Answer:

12.1, 12.3,12.4,12.5,12.3,12.1,12.2

$\bar X= \frac{12.1+12.3+12.4+12.5+12.3+12.1+12.2}{7}=12.271$

And for the standard deviation we can use the following formula:

$s= \sqrt{\frac{\sum_{i=1}^n (X_i -\bar X)^2}{n-1}}$

And after replace we got:

$s = 0.1496$

And as we can ee we got a small value for the deviation <1 on this case.

Step-by-step explanation:

For example if we have the following data:

12.1, 12.3,12.4,12.5,12.3,12.1,12.2

We see that the data are similar for all the observations so we would expect a small standard deviation

If we calculate the sample mean we can use the following formula:

$\bar X=\frac{\sum_{i=1}^n X_i}{n}$

And replacing we got:

$\bar X= \frac{12.1+12.3+12.4+12.5+12.3+12.1+12.2}{7}=12.271$

And for the standard deviation we can use the following formula:

$s= \sqrt{\frac{\sum_{i=1}^n (X_i -\bar X)^2}{n-1}}$

And after replace we got:

$s = 0.1496$

And as we can ee we got a small value for the deviation <1 on this case.

After driving 10 miles, in a 1/3 of a day, Mark is trying to figure out how many

svet-max [94.6K]

Answer:

30 miles

Step-by-step explanation:

Let the number of days = d

in 1/3 of a day, or 1/3d, he drove 10 miles

The equation is:

$10 = \frac13d$

To find out the number of miles driven in one whole day, we can multiply both sides by 3 or setting up a proportion

<h2>Method 1: Multiplying By 3</h2>

10 = 1/3d

10*3 = 1/3d * 3

30 = 1d

30 miles

<h2>Method 2: Proportions</h2>

$\frac{10}{1} = \frac13$

10*3 = 1*1 Cross multiply

30 = 1
